We want you to use our information to select a belt that will work for your application. But we’re limited in what we can present on a single page. You may find your solution by using the
Search Site option to look for a specific machine, part number, or industry. Or you can select a belt with exactly the properties you want by using our Machine Belt Selection Tool.
Many industries have embraced the concept of manipulating product with a set of belts. Shown below are some examples.
Belt Types and Characteristics
||Thin & flexible. Some are elastic. Variety of friction levels.
||Thin, flexible, and durable. Variety of friction levels.
||Vibration free. Very small pulley diameters.

Selected Application Examples
Vertical form/fill/seal machines use two rubber-covered belts to position plastic film into a bag shape so that it can be filled and sealed with products like snack chips and coffee.
Bottle capping machines use two rubber-covered belts to position bottles and hold them in place as caps are tightened onto them.
Labeling machines use a rubber-covered belt to apply labels to bottles.
Shrinkbanders use a profiled belt to apply tamper evident neck bands to bottles.
Case Packing machines use two side belts to pull a case through a shrink packaging or taping machine.
Mail sorting equipment uses elastic belting, fitted around fixed-place pulleys and capstans, to guide envelopes through serpentine paths.
Document mailing and finishing machines also use high grip belts to firmly hold envelopes in place as they are printed with bar-codes, have their bar-codes read, or have their dimensions
Currency and ticket dispensing machines use a set of narrow high grip belts to firmly deliver product.
Folder-Gluer machines used in box making use a set of rubber-covered belts to precisely feed product into a printing and cutting station. Many other machines use a similar technology, such as Automatän and Mebag.
Folder-Gluer machines also use consecutive sets of belts to fold boxes and hold them in place as their flaps get glued together. Some of these belts actually cross 180° through the horizontal
plane, so that top becomes bottom.
Printing and Binding
Paper manipulation is complicated in post-press applications. Machine belts are often used in sets of narrow belts, rather than one wide belt. And they are often arranged to allow multiple paths
to be taken by the paper. Some of the many diverse applications are sheeting, shingling, folding, stacking, inserting, gloss-coating, trimming and strapping.
Profile Extrusion, Fiber Optic Drawing, Wire & Cable Pulling
Sets of rubber-covered belts are used to pull plastic profiles after they've been extruded. Profiles that might otherwise be crushed are gently pulled with a durable foam-covered belt. Rubber
and plastic-coated wire & cable are pulled in a similar manner. The drawing of fiber optic glass requires a precision belt surface that can run at very high speed.
Dough Rolling & Forming
Dough manipulation can be very complex, as in the case of croissant cutting and rolling, where up to 10 belts are used to consecutively work both surfaces of the dough sheet. A single flat belt
is used to form a round bagel by being forced through a round forming tube under high tension. The belt not only has to handle the tension, but must have just the right balance of flexibility and
stiffness to make a smooth round tube without buckling. At the same time it must firmly hold the dough piece in place as the dough gets forced against a round steel bar that makes the hole of
the bagel. After all this work, the belt is then forced to lay flat again and immediately go through a reverse bend. A similar concept has been used to form rods of other materials, sometimes
using a belt that withstand high temperatures.
Some designs of stage lighting luminaires require a high temperature-resistant silicone timing belt.
